Mariotte siphons or Mariotte bottles (figure 1) are devices that provide a constant pressure that will deliver a constant rate of flow from closed bottles or tanks. The flow rate will depend upon the head as defined in figure 1 and not on the height of the free water surface. These devices find many uses where a nonchanging pressure is needed. One application in agriculture is for applying liquid

Of all the organisms in the natural world, green plants are the only ones that manufacture their own food. This process is called photosynthesis and begins when light strikes the plant's leaves (both sunlight and artificial light can power this process). Cells in the plant's leaves, called chloroplasts, contain a green pigment called chlorophyll which interacts with sunlight to split the water in

The propagation of plants is a very important aspect of life due to the importance of plants. The ways in which plants can be propagated are discussed due to the time that it takes to grow a plant. The fastest and most efficient way to grow plants is wanted by all the industries that produce the plants for society. I have decided to determine the fastest way of propagation by testing how cuttings

The purpose of this project is to see if gasses released in smoke enhance the germination rate of black pine seeds. I hypothesize the seeds exposed to the NO2 gas will have the highest germination rate. In order to determine if gasses released in smoke enhance the germination rate of black pine seeds, black pine seeds were obtained.

The purpose of this experiment is to see what effects gold powder has on the growth of radish seeds, if any. It is predicted that the larger amounts of gold will not increase the germination rate of the radish seeds. It is predicted that the larger amounts of gold will not increase the germination rate of the radish seeds.

Science kits, science lessons, science toys, maths toys, hobby kits,
science games and books - these are some of many products that can
help give your kid an edge in their science fair projects, and develop
a tremendous interest in the study of science. When shopping for
a science kit or other supplies, make sure that you carefully review
the features and quality of the products. Compare prices by going
to several online stores. Read product reviews online or refer to
magazines.
